HTK solution mimic extracellular fluid. Its mechanism of action is based on the principle of inactivating organ function including the heart by withdrawal of extracellular sodium and calcium in combination with intensive buffering of the extracellular space. This is achieved thanks of histidine content and prolongs the period during which the organs will tolerate interruption of oxygenated blood.
